Banknote auctions: rare and world paper money, searched at once

Banknotes are one of the fastest-growing corners of numismatics, and rare or error notes can be worth many times face value, but the market is scattered. Dedicated banknote and numismatic auctioneers run their own sales, while general auction houses regularly handle deceased-estate paper money collections that never reach a specialist catalogue at all.

See it in action: one search across the-saleroom, eBay, NumisBids and more.

Why banknote lots get missed

Specialist banknote sales are watched closely by dealers and serious collectors, which is exactly why the underpriced lots tend to sit elsewhere, a general auction listing "a quantity of banknotes" from an estate, with no idea whether it includes a rare specimen or proof note, a replacement note, or a genuine printing error. Checking every platform daily to catch these before someone else does isn't realistic for most collectors.

One search across every platform: including a numismatic specialist

Auction Bid Assistant's free browser extension searches the-saleroom, EasyLive, Bidspotter, Invaluable, NumisBids, iCollector and LiveAuctionWorld simultaneously, alongside eBay. NumisBids is itself a platform dedicated entirely to coin and banknote auctions worldwide, so a single search here already reaches specialist numismatic sales as well as the general auction houses where mis-catalogued lots hide. Search a country, series, signatory, "English banknotes," "Irish banknotes," "world banknotes," "specimen note," "proof note" or "error note" and results return across all of them, with images, estimates, current bids where shown, and sale countdowns, sorted by platform in tabs.

Real results for "banknote": 490 lots found in one search, from Hong Kong and Indian notes to 18th-century American colonial currency.

It works by searching from inside your own browser, the same as opening and searching each site yourself, just done in seconds. Nothing is stored on our servers, permissions are minimal, and the extension never places a bid on your behalf.

Alerts: for lots that don't come up often

Good banknote lots are infrequent, so save a search (a country, series, signatory, or "banknote collection" generally) and get emailed the moment a new lot matches it, across all covered platforms including eBay and NumisBids, rather than relying on remembering to check each one.

Want to try before installing?

The same search box works on this website with no install at all for eBay, iCollector, LiveAuctionWorld and Featured Auction catalogues, a quick way to see matching banknote lots before adding the rest of the platforms via the extension.

Built for how banknote collectors actually work

Save any lot with one click from search results, export your shortlist as a printable PDF or CSV before a sale, and on the day itself the optional live bridge feeds the auctioneer's asking price into the free bid calculator, so your maximum (with buyer's premium and VAT included) is always in front of you.
